In the end, the cuckooed guy decided not to kill his wife and lover (sorry ... spoiled your surprise).

For me, if this event ever happen to me. I wouldn't be so kind. There are simply too many ways to employ tact to kill off the offending joker. I am a lion and shall remain so. Live by the sword, die by the sword. It is therefore always a choice not to play other guy's women, no matter how pretty. Choose the next unattached brand new sweet young thing.

Cuckoo birds have evolved a nasty habit of laying their eggs in the nests of other bird species, who then unknowingly tend to their young. But the fairy-wren has developed a rather ingenious countermeasure: Expectant mothers teach their unhatched offspring a secret password that they'll later need to get fed. The cuckoo chicks, who don't know the password, are out of luck. There are many aspects about this discovery that are fascinating. First, it's remarkable that fairy-wrens have evolved a mechanism to thwart Horsfield's bronze-cuckoo parasitism in this fashion. For a trait to evolve like this shows just how versatile and exploratory nature can be when confronted with a problem. But given how detrimental brood parasitism is to the host bird's reproductive fitness, it shouldn't come as a surprise that evolution found a way. Fairy-wren chicks taught secret passwords to thwart dickish cuckoo birds. And as the researchers correctly point out, it's a tactic that borrows from meme theory — the notion that ideas, and not just genes, can get passed down from generation to generation and used in an adaptive way. In this case, the meme is a signature element found in a one-note chirp. Moreover, these memes — what are essentially passwords — are taught to the chicks while they're still in their eggs (what's called prenatal learning) during late incubation. So, by the time they hatch, the fairy-wren chicks already know what to ‘say' in order to prove that they're the real deal (and not a cuckoo chick). If the mother doesn't hear the proper "solicitation song," she will simply refuse to feed the chick. And fascinatingly, if the entire nest is overrun by cuckoos (or chicks who don't know the proper password), she will abandon the nest and move on to start again. Yikes.The researchers also noticed that mother fairy-wrens will teach the password to other caregivers of her young, including mates and other helpers. When they do this, however, they're out of earshot of the chicks. Which is smart. They also noticed that the signature element varies from nest to nest; all passwords are unique and tied to a particular mother. Cross-fostering experiments confirmed that a fairy-wren mother will not feed a genuine fairy-wren chick if it doesn't know the password.

This is a very sad case of a stable and reliable beta male made unwittingly to take care of another alpha male's offspring. So read the book: Sperm Wars by Robin Baker and learn well.

about me

In "1984", George Orwell paints his vision of life in an age where
totalitarianism has eradicated individuality, choice and personal
identity. In the context of a modern dystopia in the grip of political
megalomania, Orwell raises a number of concerns in connection with
modern society and the human race, while highlighting the importance of
preserving individual identity. While still a novel, 1984's core themes
are pertinent to our current world, as it draws several parallels
between the life of its protagonist, Winston, and that of the modern
man, and alludes to an important fact: identity can only exist when the
environment allows it.

1984 follows a man who has lost his identity, who does not possess
outward status of any kind and whose every move is scrutinised by those
in control. Throughout the novel, Winston seeks to be identified by
those of like mind. Eventually he meets a man named O'Brien and becomes
a criminal working against the party. Ultimately Winston is caught,
unable to overcome the regime; he is physically and psychologically
manipulated until finally he yields total obedience to his superiors.

Orwell draws a parallel between Winston and the human race as a
whole, implying that Winston is the "last man" left. The novel's
clearest message is that the human race ought not to destroy its own
identity. Orwell portrays authority as being obsessed with identifying
every aspect of its subjects, from their names to the records of their
every move. Yet it is apparent that this obsession with identification
and control leads to the destruction of every kind of meaningful
identity, since it transforms a society of unique individuals into one
of perfect homogeneity. The government's contempt for individuality is
furthered by the notion that people are classified as either sane or
insane; sanity is the equal capital crime punishable by decapitation.
